Question

What do the electrons added to NAD+ do?

a) They enter the electron transport chain
b) They combine with oxygen to form water
c) They participate in glycolysis
d) They become part of ATP

Answer 1

The electrons added to NAD+ enter the electron transport chain to generate ATP through oxidative phosphorylation.

Step-by-step explanation:

The electrons added to NAD+ play a critical role in cellular respiration. They enter the electron transport chain to generate ATP through oxidative phosphorylation. In this process, the energy from the electrons is used to pump protons across the membrane, creating an electrochemical gradient that drives the synthesis of ATP. Eventually, the electrons are accepted by oxygen to form water.
